-rpm/engine up n down (1000rpm to 500rpm) and sometime engine died....-i have changed the servo kit(some plastic gears) in the throttle area..now, after changing, my rpm starts at 1500 rpm and when down to 1000 rpm...strange..!

i changed mine 3 years back when my Wira 1.6 reached its 5th year. That time i spent RM1050 (inclusive labour, non-proton SC, should be cheaper now). advice is not to take 2nd hand unit, unless u plan to change your car in the near future. The TB has its own lifetime as well and it will break when time reaches (~6 years). If the 2nd hand unit has run for 4 years, that also means that you have another 2 years to use. If you do not have the proper tools, would advise u have it tune at the workshop. Proton SC will use the computer device to tune (more accurate readings, rpm and some other sensor readings) whereas those normal workshop will use a "light-gun" to archive the preset rpm.

Hi, I have the same problem with my 2000 wira GLI (M), any sifu can assist me to getting a OEM (APM) parts. The proton parts are very expencise yeah... Please advise what price will be reasonable ....I wouder clean up the TB will help or not ? But in the forum of WIRACLUB, DIY, do have some photo on it.... no time for thatlah....
